Vitamin D status of early preterm infants and the effects of vitamin D intake during hospital stay.

Objectives To evaluate vitamin D (vitD) status in early preterm infants (EPTIs) at birth and during birth hospitalisation on current vitD intake. Design/methods Serum 25-hydroxyvitamin-D [25(OH)D] concentrations, vitD intake and risk factors for low vitD status were assessed in 120 infants born at ≤32 weeks gestation. Results Mean (SD) serum 25(OH)D at birth was 46.2 (14.0) nmol/L with lower concentrations in infants born Conclusions Serum 25(OH)D
